Complete Wave Motion Demonstration

The PASCO SE-9600 Complete (Transverse) Wave Motion Demonstrator allows mechanical waves to be created to demonstrate the behavior and properties common to many types of waves.

Special Features

2.3 Meters Long: Plenty of room to watch the wave develop and interact.

Three Wave Sections: Each section has rods of different lengths, allowing reflection and transmission demonstrations.

Section 1 is 92 cm long with 46 cm rods.

Section 2 is 92 cm long with 23 cm rods. The resulting wave velocity is three times as fast.

Section 3 is 46 cm long with rods that vary exponentially from 46 cm to 23 cm. This section acts as an impedance-matching unit.

Yellow Rod Tips: For easy viewing and to highlight the wave motion.

Folds for Compact Storage

Easy Setup

How it Works

A series of steel rods is attached at their centers to a torsion wire. When a
rod is displaced and released, a wave propagates along the rod. Velocity depends
on the torsion constant of the wire and the moment of inertia of the rods.
